IMSResearch market the analyst JamieFox in the 2012 British International LED Exhibition (EuroLED) said, the market value of the high-brightness LEDs for general lighting applications reached a peak in 2017, then began to fall with the rapidly falling costs of technology . LED supplier's "Golden Age" in 2013 to 2017. Fox said that during this period, the LED market penetration is expected from the strong growth of a few percentage points to 10 percent in 2014 and 2017, 25%. Although the cost of the LED in the next five years may be declining rapidly, but this is 2017, in order to hinder the growth of the market value of the general lighting applications in the field of LED chips. However, after 2018, the market reached saturation, with the decline in LED prices and provide a long service life due to LED technology led lamp replacement rate, the field of general lighting applications, LED market began to shrink. LED lighting applications in the broader market will usher in significant growth from the current $ 85 billion to $ 120 billion in 2017. But with the cost reduction and saturation of the market, ten years later, the market size will shrink to 105 billion U.S. dollars. A key driver of cost reduction is one of the GaN LED chip production from the sapphire or silicon carbide substrate to the transfer of the silicon substrate, this new way of being the support of many of the major manufacturers in the industry, although varying degrees of success. Spokesman for the 2012 British International the LED Exhibition (EuroLED,): LED manufacturer BridgeLux TomvandenBussche, testing experts LUX-TSI DavidHardman Cree's DerekTibbitts and BirminghamSciencePark-Aston DavidHardman. LED chip maker Bridgelux (of Bridgelux) European Marketing Director TomvandenBussche pointed out that the LED chip production to the cost of the transfer of the silicon substrate will be reduced by 75%, which is due to the decline in silicon prices, due to the use of larger size (8 inches) the platform can take advantage of the waste has been transferred to 12-inch wafer production fab. VandenBussche adds BridgeLux will begin production before the end of the year, the silicon substrate GaN LED. The BridgeLux shows the cool white color temperature of 4700K time efficiency of 160 lumens / watt warm white color temperature of 3000K time efficiency of 125 auto dvd and bmw dvd lumens / watt silicon substrate LED, this performance has been able to match with today's most advanced devices. A key issue now is BridgeLux the possibility of mass production to achieve the same performance. If you can, then the silicon-based manufacturing methods should enable significant cost reductions, because current methods are limited to 4-inch wafer, a large number of inefficient and time-consuming stages of production, such as GaN films away from the sapphire substrate laser lift-off step.
